Anti-coup protesters in Thailand are adopting a symbol of resistance from a science fiction movie in which citizens struggle against a tyrannical government in a dark, dystopian future.

A few dozen demonstrators on Sunday gathered in a flash-mob style protest at a Bangkok shopping mall, where many held anti-army signs and raised their hands in a three fingered salute aimed at nearby troops.

The gestures were similar to those used by heroine Katniss Everdeen and other characters in “The Hunger Games: Catching Fire,” a globally popular movie based on one of Suzanne Collins’s hit trilogy of books. Western films and other popular culture are widely consumed in Thailand.
